EEZYArm bot in Shukhov Lab

CLASS – TECHNOLOGY, 3D Printing

SOFTWARE: Rhino 6, Voxelizer, Polygon, Polulu Master Control

MATERIAL: PLA & ABS 1.75 mm, bolts, screws

MACHINE: Z-Morph, Picaso Designer 250 Pro, Raise 3D

CHALLENGES: To make a 3D-Printed thing


TASK / PREPARATION

The task sounded quite simple: create something 3D-Printed. The teacher suggested making this robot for extra credits. I accepted the challenge.

The robot and all the files I took from the Instructables: https://www.instructables.com/id/EEZYbotARM-Mk2-3D-Printed-Robot/

DESIGN / PRINTING / ASSEMBLING

I transfered all the .STL files into .gcode and Polygon files to use two 3D printers, that we have in lab.

Unfortunatelly, something went wrong with Picaso Designer, that is why there was only one printer left.

I coninued printing all the parts on Z-Morph. There was a problem with the quality, that is why I got really easy-to-break details.

Low-quality deatil of the base.

The time of printing also was not so good for the details, that is why I had to print them in other places by ABS.

ABS-printed details.

ASSEMBLING / CHECK

After all parts printed, I started assembling all the details together. On the photo of ABS-printed details you can see the assembled base.

Assembling the robot

In 2 hours the Arm was assembled.

The next problem was controlling the servos.

I am using Pololu Mini Controller, that needs the outer power supply to have enough voltage to move all 4 servos.

RESULTS / REFLECTION

It was a nice challenge for me and the quality of parts, their brakings did not stop me. I went to different places to reprint the needed details, servos.

Total expendutre on the project: 5000 rubles (including servos, Pololu and 3D-printing).

It is not easy to control the robot with Pololu application. I am going to write an app to control it by the phone via Bluetooth. Also, it is possible to make it work with Arduino.

As an overall result, I have a robot-arm and knowledge of 3D Printing by different printers, connecting the servos and some coding.
